SHQEMAKERS REPAIR-JACK.

SPECIFICATION formingpart of Letters Patent No. 687,698, dated November26, 1901.

Application filed July 26, 1900.

To all whmn it may concern:

Be it known that I, DANIEL RoUNDs, a citizen of the United States,residing at Portland, in the county of Cumberland and State of Maine,have invented certain new and useful Improvements in ShoemakersRepairJacks; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

My invention relates to improvements in shoemakers repair-jacks, and isespecially designed to provide a compact and easily-adjustable machineon which can be readily placed a last for use in repairing boots andshoes.

In the drawings herewith accompanying and forming a part of thisapplication, Figure 1 is a perspective view of my improved device withthe repair-last thereon. Fig. 2 is a section of my improved device. Fig.3 isa detail view showing the end of the table. Fig. 4 is a detailsectional view of the swivel.

Same characters of reference refer to like parts in all the figures.

In said drawings, A represents a suitable stand, which I preferably makeof iron or steel in order to make it as strong and rigid as possible,and it is usually made in the form of a tripod, as shown in thedrawings. The upper ends B of the legs of the tripod are provided withsockets C, in which are inserted pivot-bolts D. Adapted to revolve on 35 said pivots is a table E. Said table consists of a suitable base E,-having a circular opening G at or about the center thereof and a bracketH on the under side thereof, said bracket being provided with an openingI,

the purpose of which will be hereinafter more fully set forth anddescribed. Adapted to rest on said table and to be revolved thereon is ahead-block J, provided with a hole K in the center thereof and adownwardly-extend- 5 ing lip L, said lip being adapted to fit in theopening G in the base F of the table. Said head-block is also providedwith a groove M upon the under side of one end thereof. On the end ofthe head-block in which is the groove there is removably attached an ad.

justable toe-rest N to serve as a support for Serial No. 24,872. (Nomodel.)

the toe portion of the last. This head-block is provided with a slot 0,so as to allow the toe-rest to be moved thereon when desired in ahorizontal direction. The object in making the toe-rest adjustable is toallow of the use of lasts of different lengths, which is absolutelyessential on devices of this kind, so as to enable the workman to repairshoes or boots of different sizes. In order to facilitate the moving ofthe toe-rest and at the same time to hold the same rigidly in positionwhen desired, I use a cam-lever P, which is pivotally connected with arod P, which extends through the slot 0 in the head-block and into thegroove M in the bottom of the head-block. On the other extremity of thehead-block I mount the heel-pin, which is attached in any suitablemanner; but as I have shown it in the drawings it is pivotally attachedto one extremity thereof by means of the ears Q and pin R. Said heel-pinis provided with a backwardly-extending lug O, which is made integraltherewith. Said lug is adapted to be held in position by means of springS, said spring extending from the extremity of the lug under theheel-pin and being held in positionby the normal downward pressure ofthe heel-pin thereon. Said H spring is further held from chance displace8o ment by means of the bolt S. My object in providing the heel-pin withthis spring is to insure the pressure of the last downwardly on thetoe-rest. It will be evident, as seen in the drawings, that when thelast is being placed on the pin the toe partjowingto the position of thepin, will extend below the toe-rest. Bycompressing the spring-that is,by lifting the toe of the last-the same will bear on the toe-rest, thespring is compressed, and therefore serves to hold the last firmly uponthe rest. In case the shoemaker desires to work on either side of theshoe, he is enabled to do so by using my improved device withoutremoving'the shoe or last from the rest. Mounted on one side 5 of thetripod is a spring T, provided with a plurality of lugs U, which areadapted to register with holes V in the table, the object of this beingto allow the headpiece and table to be moved to one side or the otherand at TOO either a right angle to the stand or at a lesser angle, if sodesired. In order to doubly insure the holding of the work on the last,I provide a strap, which is provided at one end with a suitable clasp orbuckle 2, so as to enable the strap to encircle the shoe at about theinstep. Said strap 1 is also provided with a swivel 3. Attached to thelower end of swivel 3 is a strap 4, which extends downwardly between thelegs of the tripod and is attached to a trcadle 5, which can be mountedin any suitable manner in the frame of the machine, the object of thistreadle being to tighten the strap, and thereby bring pressure uponstrap 1, which encircles the last, and to more firmly hold the work uponthe last. Strap 4 passes downwardly through the opening in the table andthrough the opening I in the bracket II. The object of having said strappass down through said opening in the table and also through the openingin the bracket is to maintain an equal strain on both straps in whateverposition the table may be placed, and this is accomplished especiallyfrom the fact that the lower side of the bracket His in axial alinementwith the bolt D, from which it is clearly evident that no matter in whatposition the head-block is moved on said pivot D there will always be auniform strain on the straps. In order to obviate any rocking movementor motion of the head-block, I place the raised portions or tracks F onthe table E. These are placed at some distance from the center of saidtable and they serve as a steadying means for the head-rest and save anyunnecessary rocking or wear of the lip L. Other means may be employedfor holding the revolving table in position, and I do not wish to belimited to the exact manner of holding said table in position asdescribed in the specification,the form described beingpreferably usedby me; but other means and different positions of the locking-bolt maybe used without departing from the spirit and intent of my invention.

Having thus described my invention and its use, I claim- 1. Inarepair-jack, in combination, a stand, a table having a central circularopening therein pivotally mounted on said stand, and adapted to have aswinging movement thereon, one end of said table having openingstherein, a spring carrying a plurality of lugs, said lugs adapted to fitinto the openings in the end of said table, a bracket having a centralopening mounted on the lower side of said table, the lower side of saidbracket being in axial alinement with the pivots holdin'g said table, ahead-block pivotally mounted on said table, said head-block having anopening in the center thereof and straps concargoes nected by a swivel,one of said straps running through said openings in the head-block,table and bracket, and attached to a pedal on the stand.

2. In a repair-jack, in combination, a stand, a table having a centralcircular opening therein pivotally mounted thereon and capable of havingmovement from one side to the other of the stand, a bracket with anopening in the center thereof attached to the lower side of said table,the opening in said bracket registering with the opening in said table,the lower side of said bracket being in axial alinement with the pivotsholding said table in position, a head-block having an opening in thecenter, mounted on said table and adapted to be moved thereonindependently of any movement of said table, a toe-rest on saidhead-block adjustable horizontally, means for holding said toe-rest inany desired position and a heel-pin provided with a rearwardly-extendinglug, said pin being normally inclined toward said toe-rest, and a springcarrying lugs adapted to register with openings in the end of the table.

3. In a repair-jack, in combination, asuitable stand, a table having acentral circular opening therein pivotally mountedthereon and adapted tobe moved from one side to the other of the stand,a bracketwith anopening in the center thereof, the openingin said bracket registeringwith an opening in said table, the lower side of said bracket being inaxial alinement with the pivots on which the table is mounted, openingsin one end of said table, a spring mounted on said stand and providedwith lugs, which lugs are adapted to fit into the openings in the end ofsaid table to hold the same in any desired position, a headblock, adownwardly-extending lip mounted on said head-block, said lip extendinginto the circular opening in the table, a foot-lever pivotally mountedon said stand, straps conneeted by a swivel, one of said straps runningthrough the openings in said head-block, table and bracket to a lever,an adjustable toe-rest, a spring-controlled heel-pin, arearwardly-extending lug made integral therewith, said heel-pin beingnormally inclined toward the toe-rest, and means for preventing saidhead-block from rocking on the table.

In testimony whereof I affix my signature, in presence of two witnesses,this 10th day of July, 1900.
